+Yardstick Test Case Description TC037
+*************************************
++-----------------------------------------------------------------------------+
+|Network Performance |
++==============+==============================================================+
+|test case id | OPNFV_YARDSTICK_TC037_NW PERF |
++--------------+--------------------------------------------------------------+
+|metric | Number of flows, latency, throughput, CPU load, packet loss |
++--------------+--------------------------------------------------------------+
+|test purpose | To evaluate the IaaS network performance with regards to |
+| | flows and throughput, such as if and how different amounts |
+| | of flows matter for the throughput between hosts on different|
+| | compute blades. Typically e.g. the performance of a vSwitch |
+| | depends on the number of flows running through it. Also |
+| | performance of other equipment or entities can depend |
+| | on the number of flows or the packet sizes used. |
+| | The purpose is also to be able to spot trends. Test results, |
+| | graphs ans similar shall be stored for comparison reasons and|
+| | product evolution understanding between different OPNFV |
+| | versions and/or configurations. |
++--------------+--------------------------------------------------------------+
+|configuration | file: opnfv_yardstick_tc037.yaml |
+| | |
+| | Packet size: 64 bytes |
+| | |
+| | Number of ports: 1, 10, 50, 100, 300, 500, 750 and 1000. |
+| | The amount configured ports map from 2 up to 1001000 flows, |
+| | respectively. Each port amount is run two times, for 20 |
+| | seconds each. Then the next port_amount is run, and so on. |
+| | |
+| | During the test CPU load on both client and server, and the |
+| | network latency between the client and server are measured. |
+| | |
+| | The client and server are distributed on different HW. |
+| | |
+| | For SLA max_ppm is set to 1000. |
++--------------+--------------------------------------------------------------+
+|test tool | pktgen |
+| | |
+| | (Pktgen is not always part of a Linux distribution, hence it |
+| | needs to be installed. It is part of the Yardstick Glance |
+| | image. |
+| | As an example see the /yardstick/tools/ directory for how |
+| | to generate a Linux image with pktgen included.) |
+| | |
+| | ping |
+| | |
+| | Ping is normally part of any Linux distribution, hence it |
+| | doesn't need to be installed. It is also part of the |
+| | Yardstick Glance image. |
+| | (For example also a Cirros image can be downloaded from |
+| | https://download.cirros-cloud.net, it includes ping) |
+| | |
+| | mpstat |
+| | |
+| | (Mpstat is not always part of a Linux distribution, hence it |
+| | needs to be installed. It is part of the Yardstick Glance |
+| | image. |

++--------------+--------------------------------------------------------------+
+|applicability | Test can be configured with different packet sizes, amount |
+| | of flows and test duration. Default values exist. |
+| | |
+| |SLA (optional): |
+| | max_ppm: The number of packets per million packets sent |
+| | that are acceptable to lose, i.e. not received. |
++--------------+--------------------------------------------------------------+
+|pre-test | The test case image needs to be installed into Glance |
+|conditions | with pktgen included in it. |
+| | |
+| | No POD specific requirements have been identified. |
++--------------+------+----------------------------------+--------------------+
+|test sequence | step | description | result |
+| +------+----------------------------------+--------------------+
+| | 1 | The hosts are installed, as | Logs are stored |
+| | | server and client. pktgen is | |
+| | | invoked and logs are produced | |
+| | | and stored. | |
++--------------+------+----------------------------------+--------------------+
+|test verdict | Fails only if SLA is not passed, or if there is a test case |
+| | execution problem. |
